I still have a question, I have already installed the Win2K into 2 machines,one is Fileserver(Domain-controller) and another one is Mailserver(Exchange,and it is also the Additional Domain controller now).
However, I need to modify the domain configured in the Fileserver(Primary Domain Controller), I need to demote it by Removing the Active-Directory,then I found that my Service-account is disappeared. So I can't logon as
this service-account to manipulate any things about Exchange-server services.
I can't do anything even I re-create an other service-account MSEXCHANGE with the same ID & password & Administrator-right (same as the original SERVICE-ACCOUNT). I can't do anything with this powerful-user right.
Then I try to run the setup to re-install everything and overwrite the existing things, the system discourage me to do anything. I get just stuck in this scenario.
Some questions:
1) Can I overwrite the existing complete-installation without the original service-account ? And I even can't use
the DOMAIN-Administrator logon to run the Exchange-CD setup.exe right now!
